Connection

3 fields, 1 required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.

is_private Create it as a private channel rather than a public one.	boolean	No	false	—	—
team_id Workspace to create the channel in. Only needed with an org-wide token.	string	No	—	—	—

Every value below is the contract’s own example or default — nothing invented.

The bot must be a member of a private channel before it can act there (Slack answers not_in_channel otherwise).
Slack rate-limits each Web API method on its own tier; a throttled call fails with the number of seconds to wait and is safe for the node's retry policy to repeat.
Slack lower-cases the name and replaces spaces, so the id is the safe handle.

In a technical demo we add the Slack connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
